Harmonic Highlights

  • Tonicization of the iii (C minor) via Cm6 and G7alt, which creates a sophisticated, dark modal contrast within the primary Ab major framework.
  • Frequent secondary ii-V progressions (F7-Bbm7 and Ab7-Dbm7) that cycle through closely related keys, delaying definitive resolution to the tonic.
  • Chromatic descending dominant chains (E7-Eb7-D7) utilizing parallel motion and tritone substitutions to navigate back to the G7alt turnaround.

Improvisation Focus

C Melodic Minor / G Altered scales to effectively navigate the frequent shifts into the C minor tonal center.

Difficulty Rating

4 (Advanced) โ€“ The rapid modulation through multiple temporary key centers and non-diatonic dominant chains requires high-level harmonic awareness and fluent scalar shifting.
